Subject: [PATCH] Create cohort_characterization_version on installs from the
 3.0 baseline

The B2.99.0006 baseline creates the version tables for cohorts, concept
sets, incidence rates, pathways and reusables but not for
characterizations, so on a fresh install every characterization update
fails with SQLGrammarException while saving the previous version.
Create the table if it is missing; databases upgraded from 2.x already
have it.
